PISTON -RI1\'|'G COMPRESSOR.

Specification of Letters Patent.

Patented July 15, 1919.

Application filed January 22, 1919. Serial No. 272,531.

To all whom it may concern:

Be it known that I, LOUIS ALBAUM, a citizen of the United States,residing at Everett, in the county of Middlesex, State of Massachusetts,have invented a new and useful Piston-Ring Compressor, of which thefollowing is a specification. I

My invention relates to piston-ring compressors of that type whichcomprises a flexible pistonring-compressing element adapted to encirclethe piston-ring, and a pair of tongs-like or plier-like elementsengaging the flexible piston-ring-compressing element and operating totighten the same around the piston-ring to compress the latter; and theobject of the invention is to provide an improved device of this naturewhich is simple and inexpensive to manufacture and which is thoroughlyefficient in operation and which has other advantages, all as will bemore fully hereinafter set forth.

In order to give an understanding of my invention, I have illustrated inthe drawing a selected embodiment thereof which will now be described,after which the novel features will be pointed out in the appendedclaims.

The single figure in the drawing shows in. perspective a piston-ringcompressor embodying my invention.

In the drawing A indicates a piston-ring to be compressed, the pistonwhich is associated with. said ring being omitted for the sake ofclearness.

My improved piston-rin 'compressor comprises a pist-on-ring-compressingelement in the form of a wire, cable or cord D and a novel tongs-likeelement E which is connected to the ends of the cord D. This tongs-1ikeelement E comprises two levers 2 and 3 pivotally connected at l, saidlevers having the jaws 5 and 6, respectively. The jaw 6 of the lever 3is provided at its ends with the laterally-extending flange B having anaperture therein through which the cord D extends, the end G of saidcord being enlarged in some suitable way to prevent it from pullingthrough the aperture. The jaw 5 of the lever 2 is provided with theflange portion '7 against which the cable D is adapted to rest and theclamp F constructed to clamp adjustably the cord to theflange '7. Saidjaw 5 is also provided at its end with an open-ended guiding slot 8through which the cable 'or cord D extends and which guides it to theclamp F. This slot 8 is formed by providing the jaw 5 with the finger Gex tending parallel to the flange 7 at theend thereof. The clamp F is inthe formof an arm 9 which extends substantially parallel to the flange 7and a clamping screw which is screw-threaded in said arm and is adaptedto be screwed against the cord D. The arm 9 projects in a directionopposite to the finger C so that said arm holds the cord in the slot 8and the finger C and slot hold the cord under the arm 9.

In using the device, the clamp F is loosened and the cord or cable isdrawn through the slot 8 and clamp 9 until it fits snugly around thepiston-ring, as shown in the drawing, and the clamp is then tightened.-

The application of pressure to the levers 2 and 3 will close the jawsand thus operate through the cord to compress the pistonring in awell-known way. The use of the open slot 8 and the form of clamp- Fenables the cord D to be readily removed from the jaw 5 whenever it isdesired to do so by simply withdrawing the cord out through the open endof the slot and oubfrom under the arm 9.

I claim:

1. A piston-ring compressor comprising a flexible piston-ring-compressing element adapted to encircle a piston ring and atongs-like element having two jaws, one of 1 which is provided with alaterally-extending apertured flange through whichone end of theflexible member extends and the other of which is provided with asupporting flange, a clamp for clamping the other end of said flexiblemember thereto, and a guiding slot through which the flexible memberextends.

2. A piston-ring compressor comprisin a flexible cord adapted toencircle a pistonring and a tongs-like element having two jaws, one ofwhich is provided with an apertured lateral flange through which one,end of the flexible cord passes and the other one of which is providedat its end with a guiding slot to receive said cord. and means forclamping the cord adjusta'bly to said other aw. J 3. A piston-ringcompressor comprising a flexible cord, two levers pivotally connected;together intermediate of their ends and each provideclwith a jaw, onejaw having a laterally-extending apel'tul'ecl flange at its end 5through which the flexible cord extends, and the other jaw having asupporting flange,

an arm extending parallel to said flange, a. clamping screwscrew-threaded through said arm and adapted to clamp the cord to theflange, and a guiding slot at its end to guide 10 the cord to theclamping means.

LOUIS ALBAUM.
